turning off new-style classes

is there an easy way to revert to 0.9-pre-16 behaviour of creating
"old-style" classes? zope's security seems to choke on new-style---or
is there a way to make it work with new-style classes?

attached is the __init__.py I use in zope... maybe somebody can
enlighten me on a better way to do it?

/me is in total newbie mode
